To all whom it may) concern:

Be it known that 1, CHARLES U. Coeznns, a citizen *of the United States, residing at Elouthbridge, in the county of Worcester and State of llfassachusetts, have invented certain new and useful improvements in Eye Protectors of which the following is aspecification.

This invention relates to improvements in eye protectors and has particular reference to an improved type of protector especially adapted for use in welding or similar industries. v

Une of the principal objects of the present invention is the provision of a novel and improved type of goggle or eye protector capable of general'use, but particularly applicable to welding; operations, which shall be provided with improved simple and efficient means for securing proper and desired ventilation of the interior of the eye cup, while absolutely preventing any direct heat or light radiations from entering; said cup. i

A. further object of the present invention is. the provision of a novel and improved construction of eye protector which shall be so constructed to automatically adapt itself to varying configurations of faces to make a proper tight and comfortable fit with said faces, and which while so properly fitting and conforming tothe requirements of the individual wearer shall be constructed to make useof a standard size and shape of lens.

"Other objects and advantages of my pres ent invention should be readily apparent by reference to the following; specification taken; in connection with the accompanying drawings and it will be understood that it may malre any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of the invention.

Figure l represents a front view of a protector embodying my improvements.

Figure llll represents a plan view thereof.

Figure llltll represents a vertical sectional view taken as on the line l[l[l[--l[l[ll of Figure Figure llV represents a front view of the eye cup with cap and lens member removed.

Application filed March 22, 1920. Serial No. 367,680.

F igure Vlill illustrates another type of ventilation.

In the construct-ion of eye protectors for those engaged in welding or similar operations. in the past difficulty has been experi enced due to the fact thatit is quite undesirable to make use of metal eye cups and the like on account of the intense heat to which the parts are subjected so that composition or non-metallic members of larger size and bulk incapable of bending' adjustments possible wit-h ordinary metal forms of protection have been required.

A further difliculty eirperienced in this dircction is that of securing proper ventilation so that the inside of the eye cup when ti ghtly held agz'iinst the face will not 'liieco-n'ie dried up by the heating operations, 7 comfort to the wearer, but in which there shall be a free circulation. of air counteracting this drying up GllI QClJL flare, however, has to be hZl-lIBll that in securing; this circulation of air no direct light radiations enter the cup to cause injury to the vision of the wearer through the presence of harmful. radiations or intense heat.

in the attainment, therefore, of the fore going advantages ll form my improved eye protector with a cup portion 1., provided with a rearwardly deflected curving skirt portion 2 of shape to fit around. the side of the face of the wearer, and. with a central slightly inwardly curved bearing portion 3 adapted to fit into the socket between. the side of the nose and the eye, the portion 3 beingprovided with a lug 4: slotted as at 5 to receive the bridge member 6. P aid bridge member 6 is of flexible material. and has ears 7 securing it in position within the slot. The skirt 2 is likewise formed with a slotted lug 8 to receive the head band 9 for retaining the protector in position.

lfn that form of the invention illustrated in detail in Figures lfllli and IV, is to be found one embodiment of my improved ventilation structure, in that the cup 1 is procausing; di s- V vided on its front face with the notches 10 leaving the upstanding abutment lugs 11 against which rest the lens 12 secured in position by the flange 13 of the screw cup 1st which screws around the outer face of the lug 11. It will thus be seen that a space is provided at the notches 10 between the lens and adjacent portion of the cup wall 2, while communicating with this space is the recess or groove 15 formed by grooving or milling a slot in the side of the cup communicating with the notch 10, as should be best understood by a comparison of the structure shown in Figures III and IV. There is thus a plurality of air circulation or ventilation passages formed by the combined effect of the notches 10 and grooves 15. Ingress of either foreign particles, rays of light or the like, is prevented by the fact that the outer wall or cup 14 is screwed over the lugs 11 on their outer side to at one time hold the flange portion 13 in place, clamping the lens 12 against the outer face of the lugs and overlying the major portions of the passages 15 so that any light rays tending to enter the cup at the passage must extend up through the curved passage and then bend at right angles through the cup wall 2 so that all light, heat or chemical rays are excluded from the interior of the cup, although perfect ventilation is obtained, while the liability of flying particles entering the same is reduced to a minimum.

In Figure V, I have shown a slightly modified form of the invention, in which in place of the grooves and notches the wall of the cup 1 is provided with apertures 16 overhung by the skirt 17 on the lens holding cup 14, producing substantially the same offeet as in Figure III, although with a slightly different type of construction.

Figure VI illustrates a molded form in which through the use of gores the reversely leading passages 18 are formed in the walls 2 of the eye cups, and again a passage is provided reversely extending inaccessible to rays of light from the front or side, but providing free ventilation and circulation of air.

Figures VII and VIII illustrate a further form of the goggle or protector provided with these reversely extending passages W.

In Figure VII the lens placed interiorlv of the cup and retained in position by the locking ring 20 screwed into the inside of the cup in place 01 a cap meinliier screwed on the outside, this allowing a slight reduction in the outside diameter of the lens retaining member.

Figure VIII shows the same molded shirt portion 21 overlying the passage 15) lllll. with the cap 11 screwed exteriorly thereon to clamp in position the lens 19.

From the foregoing specification taken in connection with the accompanying drawings the construction of my improved goggle. should be readily understood, and it will he seen that I have provided an improved construction which may be readily molded or formed, and in which correct ventilation with elimination of any light and heat radiations from the interior of the cup, is obtained.

I claim:

1. An eye protector including a composition cup portion formed with exterior grooves tcrn'iinating in inwardly extending notches, and a lens retaining cup member fitting the cup and spanning the notches and grooves whereby the latter provide passages communicating with the interior of the cup.

2. A composition eye n'otecl'ior including non-metallic cup portions lormcd with integral late ally 'n'ojecting lugs formed to receive connecting and howl-engaging members. said cups being formed at their for ward ends with lens-engaging seats and hav ing relieved portions providing passages adacent said seats. and retaining clip members overlying the lens and adjacent portion of the cups and in close engagement with the periphery of the cups but overlying the relieved portions whcrcliy the latter provide ventilation passages.

In testimony whereof I have allixcd my signature, in presence of two witnesses.
